COMBINED which the following is a specification, reference being had therein to the accompanytaken on thelme Y--Y of Fig.

ing drawing.

Specification 01 Letters Patent.

This invention relates to a combined water and steam radiator of that class where the water is contained in certain parts of the radiator where it may be heated by the admission of steam in such a way that all of the advantages of a hot water'heating system may be obtained with a less amount of fuel than thatrequ'ired forthe usual water system, as it requires much less fuel to generate sufficient steam to heat the water than it does to directly heat the water, owing to the fact that in a combined system the water does not have to circulate and thus retains the heat fora longer time.

The objects of the invention are vide a combined radiator that may on either a single or a be used of both the hot water and the steam systems. \Vith these and other objects in view my invention consists in certain construction and combination of parts as will hereinafter be fully described and claimed herewith, and fully illustrated in the accompanying drawings, which form a part of this application and in which like figures of reference refer to corresponding parts in all of the views; but it is fully understood that while I have invention as shown, that I do not confine myself to the exact construct-ion asshown, as slight changes may be made within the scope of the claims without departing from the spirit of the invention.

' In the drawiugs:--Figure 1, is a side ele- "vation of a radiator embodying my construction as. applied to a doublepipe system. Fig.2, is an end view of the same. Fig. 3, is a vertical sectional view, taken on the line X--X of Fig. 2. Fig.- 4, is a vertical sectional view of one ofthe combined coils,

1. Fig. 5, is a horizontal section, Z-Z of Fig. 1

Referring to the drawings, the radiator comprises the series of intermediate water taken on the line to prodouble pipe system and that shall combine all of the advantages here described my usual way of the end coils 4,

water to the level of the top'of the wall 5,

the top and bottom,

sections or coils 1, of pattern, which are connected together in the by the nipples 2, rods 3. The end sections or-c oils 4, and 9, are divided vertically by an integral wall 5, which extends to within a short, distance'of the top, thus dividing said coil'into a water compartment 6, and a steam compartment 7 the outer compartment 7, communicating with the inlet pipe 8, attached to one of said end sections 4, and the inner compartment 6, communicating and the i stay both at the top and botthe usual double hub I tom with the adjacent -coil"-1-; said wall 5,

thus closes communication between said chambers or compartments 6, and 7, except near the top of said coil 4, and as governed by the valve 10,- which is placed near the bottom of said coil 4. The end section or 0011 9, is constructed in like manner, except that the outer chamber 7, is attached to the outlet pipe 11, and it is provided with the air cock 12, and with no opening 111 the wall 5; and as stated, in a single'pipe system this-second divided coil may be dispensed with and the usual coil used.

Referring to a the drawings pipe system; it will be seen that the intermediate'section 1, and the inner chambers'ti, having been filled with steam may be admitted through the inlet pipe 8, into the outer chamber 7, of the coil 4, and said steam will circulate upward throughsaid chamber 7 and through the upper hubfof the coils over the surfacev of the water and downward through the chafrfher 7, in the opposite end coil to the outlet pipe '11,thus heating the water with aminimum amount of steam.

o fill the radiator 'Wltl'! water, the water may be admitted through the inlet [steam water chambers are filled pipe 8, until the, j and then the chamber 7, may be drained off. and to empty the radiator the valve 10, may be opened allowing the water to escape from the coils through the inletpipe'.

Having thus I claim as new and desire to secure by Letters Patent is 2- v 1. A'radiator comprising a series of sections communicating with one another at the-end section being a vertical partition dividing chamber and a water champrovided with it into a steam her, said chambers having communication above. the communication of the double described my invention what between the sections at the top of the radialtor; said steam chamber formedwith a steam inlet whereby the Water within the sections may be heated and circulated by 5 admission of steam to the steam chamber.

10 ing it into a steam chamber and a water chamber, said chambers having communication with each other above the communication between the sections at the top of the =radiator, said steam chamberformed with a steam inlet whereby the water within the sections may be heated andcirculated by admission of steam to thesteam chamber, and a valve placed in said vertical partition on a level with the lower end thereof for the purpose of draining the water from said radiator. v

In testimony whereof I afiix my signature in presence of two witnesses.
